Birdperson asks if Morty knows what "wubba lubba dub dub" means, and Morty says it's just Rick's dumb catchphrase. Birdperson reveals that in his native tongue, it actually means "I am in great pain, please help me." Morty says that Rick isn't really that deep, and is just saying it ironically, but Birdperson tells him that Rick really is in great pain, and needs Morty there with him.
